Snapcraft 指南 (Ubuntu 软件中心 & 更多)

    与更广泛的 Linux 社区一起, 规范旨在解决 项目中的许多常见的软件安装问题。 Snaps 是容器化的软件包, 包括所需的依赖项、自动更新和对所有主要 Linux 发行版的工作, 而无需进行系统修改。

    创建 .snap 文件有三种方法:

    1) 使用 或 electron-builder, 与 snap 支持的两个工具都不在该框中。 这是最简单的选择。 2) 使用 electron-installer-snap, 它采用 electron-packager 的输出。 3) 使用已经创建的 .deb 包。

    在所有情况下, 都需要安装 snapcraft 工具。我们建议在 Ubuntu 16.04 (或当前的) 上建立。

    该模块的工作原理与类似 因为它的范围仅限于构建捕捉包。 你可以这样安装:

    1. npm install --save-dev electron-installer-snap

    打包应用程序使用 electron-packager (或类似工具)。 Make sure to remove node_modules that you don't need in your final application, since any module you don't actually need will increase your application's size.

    结构输出应该看起来大致像这样:

    From a terminal that has snapcraft in its PATH, run electron-installer-snap with the only required parameter —src, which is the location of your packaged Electron application created in the first step.

    1. npx electron-installer-snap --src=out/myappname-linux-x64

    Snapcraft is capable of taking an existing .deb file and turning it into a .snap file. The creation of a snap is configured using a snapcraft.yaml file that describes the sources, dependencies, description, and other core building blocks.

    If you do not already have a .deb package, using electron-installer-snap might be an easier path to create snap packages. However, multiple solutions for creating Debian packages exist, including , or .

    For more information on the available configuration options, see the documentation on the snapcraft syntax. Let's look at an example:

    1. name: myApp
    2. version: '2.0.0'
    3. summary: A little description for the app.
    4. description: |
    5.  You know what? This app is amazing! It does all the things
    6.  for you. Some say it keeps you young, maybe even happy.
    8. grade: stable
    9. confinement: classic
    10. parts:
    11.   slack:
    12.     plugin: dump
    13.     source: my-deb.deb
    14.     source-type: deb
    15.     after:
    17.       - desktop-gtk3
    18.     stage-packages:
    19.       - libasound2
    20.       - libnotify4
    21.       - libnspr4
    22.       - libnss3
    23.       - libpcre3
    25.       - libxss1
    26.       - libxtst6
    27.   electron-launch:
    28.     source: files/
    29.     prepare: |
    30.       chmod +x bin/electron-launch
    32. apps:
    33.   myApp:
    34.     command: bin/electron-launch $SNAP/usr/lib/myApp/myApp
    35.     desktop: usr/share/applications/myApp.desktop
    36.     # Correct the TMPDIR path for Chromium Framework/Electron to ensure
    37.     # libappindicator has readable resources.
    38.     environment:
    39.       TMPDIR: $XDG_RUNTIME_DIR

    As you can see, the snapcraft.yaml instructs the system to launch a file called electron-launch. In this example, it passes information on to the app's binary:

    1. apps:
    2.   myApp:
    3.     # Correct the TMPDIR path for Chromium Framework/Electron to ensure
    4.     # libappindicator has readable resources.
    6.     desktop: usr/share/applications/desktop.desktop
